DNS Level Blocking

[Bourbonated]

G'evening.

As the topic states, I wish to ask about DNS Level Blocking. Has anybody experienced this lately with their ISP? I have found a few sites lately that have blocked by my ISP. I did not realize that this was a thing in Australia (For the moment). Luckily this is easy to circumvent, for the minute.

Are you certain it was your ISP? Circumvent? It's DNS, there's no way any ISP can control it (only APNIC with au's). Use a real DNS server; 8.8.8.8 (8.8.4.4 secondary), our friends Google block no site.

Do you mean filtering?

Yeah, I am certain it was my ISP, lol. I just let my modem set it's own DNS for a little while. Tried pinging and tracert'ing the website to no avail. Simply changed my DNS under the adapter settings to the Google DNS and everything was fine. Of course, if I was to ring them and ask them why, the would just shrug it off.

I find it hilarious, to be perfectly honest.

Who's your ISP? Maybe they just had a nameserver issue? I mean if you were going to block a site, you wouldn't use DNS, you'd use some sort of perimeter appliance and force your clients through it.

While that quite true, I would hate to think Dodo would actually have the resources to pull it off. It would be a massive financial pitfall for them, if they did.

Lol, dodo don't even have their own infrastructure, they buy services from the lowest common denominator, which may as well be a cluster of HP desktops iiNet threw in a bin. It was a fault mate, no question.

Just a FYI for anyone who is using an external (out of country) DNS server. This is not a recommended practice, nor will you see much of an improvement in browsing speeds.

The reason for this is is that they stuff up your computer's ability to find the closest Akamai server to you.

Akamai is the worldwide system which places massive file servers inside ISP data centres worldwide. Which basically acts like a giant cache so that when you download a big file like a Windows or Mac OS X update, something from iTunes, it downloads from a server that's very close to you, and therefore helps speed up the download as there are fewer bottlenecks.

Using Google's DNS or OpenDNS is fine for testing and troubleshooting, but in the long run you are far better off using a local DNS server for DNS lookups.

Google's DNS farms aren't OS, OpenDNS are. Ping 8.8.8.8, then ping your ISP, for example iiNet: 203.0.178.191. Latency is the same or a couple of ms in favour of one or the other.
